Fix Device Manager Code 10: "This device cannot start"

What to do first

For Code 10, record any additional failure message and the driver version, then isolate the start failure using Windows Update, the manufacturer's official driver, and redetection.

This is a general troubleshooting guide, not an announcement of a current outage.

Before you start

  • Record the device name, complete status message, and driver provider, date, and version

Step-by-step instructions

  1. 01

    Record the error details

    #

    In Device Manager, right-click the affected device > Properties. Note the device-specific message following Code 10 on the General tab and the provider and version on the Driver tab.

    Open Device Manager from Windows key+X. Confirm that the affected device's General tab says "This device cannot start. (Code 10)" and save all text that follows without omitting anything. Do not assume Code 10 from a yellow symbol alone.

  2. 02

    Complete pending updates

    #

    Select Settings > Windows Update > Check for updates. Under Advanced options > Optional updates, select a driver only if one is available for the affected device, then restart.

    In Windows 10, open Settings > Update & Security > Windows Update. If optional driver updates are available, select View optional updates and check for the affected device.

  3. 03

    Update the driver

    #

    Right-click the device > Update driver > Search automatically for drivers. If none is found and Code 10 persists, check the PC or device manufacturer's support page for a driver matching the exact model and Windows version.

    On the manufacturer's download page, check the OS version, 32-bit/64-bit or ARM support, and exact device model. For built-in laptop devices, prioritize the PC manufacturer's supported combination. If the installer requests a restart, complete it before comparing the status.

  4. 04

    Redetect the device

    #

    Right-click the device > Uninstall device. On the first attempt, do not select the option to delete the driver; restart instead. After Windows redetects the device, reopen its status.

  5. 05

    Compare the hardware

    #

    For an external device, try another port, cable, and PC. For a built-in device, run the PC manufacturer's diagnostics. If it cannot start in another environment either, give the manufacturer the device-specific message you recorded.

    For a built-in device that cannot be moved to another PC, there is no need to try removing or disassembling it. Tell the PC manufacturer the model, full Code 10 message, current driver version, and that updating did not help, and ask for model-specific diagnostics.

Check the result

  • Device status says "This device is working properly"
  • The device's actual functions, such as network connectivity or audio playback, work

If the problem continues

  • If this began immediately after an update, check whether Driver > Roll Back Driver is available
  • For built-in devices, give the PC manufacturer the diagnostic code and driver version

Scope of this guide

Troubleshooting guide — Ensure that the device starts and its properties report normal operation.

Frequently asked questions

Are Code 10 and Code 43 the same?

No. Code 10 means Windows cannot start the device. Code 43 means the driver has reported a device failure to Windows.

Automatic search says the best driver is installed, but the problem remains.

Check whether the PC or device manufacturer provides a model-specific driver and include the complete error message when contacting support.
